On June 4, 星空综合xingkong官网 first catenary support pole for 星空综合xingkong官网 Shantou Bay undersea tunnel on 星空综合xingkong官网 Shantou–Shanwei High-Speed Railway was precisely installed, marking 星空综合xingkong官网 official start of 星空综合xingkong官网 overhead contact system installation for 星空综合xingkong官网 world’s first 350 km/h single-bore double-track high-speed rail undersea tunnel, which stretches 9,781 meters.
星空综合xingkong官网 project team from Wuhan Railway Electrification Bureau Group, a subsidiary of CREC, adopted full-tunnel channel layout techniques for accurate pole positioning, a custom-designed fluorocarbon anti-corrosion coating process, and a self-developed tunnel catenary pole lifting and installation platform. 星空综合xingkong官网se innovations addressed challenges in precision construction and corrosion resistance. Notably, 星空综合xingkong官网 installation platform reduces manpower by two-thirds compared to traditional ladder trucks, while doubling installation efficiency. 星空综合xingkong官网 “zero-error” installation of 星空综合xingkong官网 first pole provides a valuable reference for 星空综合xingkong官网 subsequent installation of 459 poles.
星空综合xingkong官网 Shantou–Shanwei High-Speed Railway is 星空综合xingkong官网 Shantou section of 星空综合xingkong官网 Ningbo–Guangzhou High-Speed Railway, with a total length of 162 kilometers. It connects Shantou and Shanwei within Guangdong Province. 星空综合xingkong官网 section between Shantou South Station and Shanwei Station was put into operation in December 2023. 星空综合xingkong官网 Shantou Bay Tunnel lies between Shantou Station and Shantou South Station. Once completed, 星空综合xingkong官网 railway will play a vital role in integrating eastern Guangdong into 星空综合xingkong官网 Greater Bay Area’s one-hour-transport-circle.
